Biological Damage Of UV Radiation In Environments Of F-type Stars
Sato, Satoko (Physics, 2014-07-14)I investigate the general astrobiological significance of F-type main-sequence stars with special consideration to stellar evolutionary aspects due to nuclear evolution. DNA is taken as a proxy for carbon-based macromolecules ... -
Case Studies Of The Circular Restricted Three Body Problem
Eberle, William Jason (Physics, 2007-08-23)In this thesis, the onset of instability for a planet which is part of a stellar binary system is investigated by running numerical simulations of the circular restricted three body problem. This study also makes use of a ... -
Habitability of Stellar Binary Systems
Wang, Zhaopeng; 0000-0001-7421-5264 (2017-09-18)A comprehensive approach is provided to the study of habitable zones (HZs) for both S-type and P-type cases of stellar binary systems for both circular and elliptical orbits of the binary components, based on habitability ... -
Selected Studies Of Orbital Stability And Habitability In Star-planet Systems
Eberle, William Jason (Physics, 2011-03-03)The study of planets remaining in orbit around one star with another starinterfering is an important topic of orbital mechanics and astrobiology. The onset of instability for a planet which is part of a stellar binary ... -
Semi-empirical Studies Of Solar Supergranulation And Related Phenomena
Williams, Peter Edward (Physics, 2008-09-17)In recent years, solar observations have moved from ground-based telescopes to observatories on Earth orbiting satellites, such as SOHO. They provide us with a clear and uninterrupted view of the solar disk. One instrument ... -
A Study Of Ejection Times Of Terrestrial Planets From The Habitable Zones Of The Solar Twins Hd 20782 And Hd 188015
Yeager, Katherine Elizabeth (Physics, 2009-09-16)We provide a detailed statistical study of the ejection of Earth-mass planets from the habitable zones of the solar twins HD 20782 and HD 188015. These systems possess a giant planet that crosses into the stellar habitable ... -
THE RESPONSE OF IONOSPHERE AND THERMOSPHERE TO THE HIGH LATITUDE ENERGY DEPOSITION
Lu, Yang (2018-12-10)The ionosphere and thermosphere are the important regions in the Earth upper atmosphere. They represent the ionized and neutral particles, respectively. The main external energy sources in those regions are solar radiation ... -
Tracking Stellar Activity Enhancements Due To A Close-in Giant Planet In The HD 179949 System
Gurdemir, Levent (Physics, 2010-07-19)We monitored CaII H and K lines (3933Å and 3968Å) of the HD 179949 system to study Planet Induced Emission (PIE) as an effect of star-planet interaction. We obtained high resolution spectra (R > 50,000) with high signal-to-noise ...
